Detailed Description

template<typename GUM_SCALAR>
class gum::prm::PRMScalarAttribute< GUM_SCALAR >

<agrum/PRM/elements/scalarAttribute.h>

PRMScalarAttribute is a member of a Class in a PRM.

A PRMScalarAttribute is defined by its name, its containing class, its type and by a Conditional Probability Function (aka CPF but represented by a Potential).

An attribute in a PRM is the equivalent of a random variable in a bayesian network.

This class is constructed by a gum::PRMFactory and is deleted by its gum::Class.

Built-in copies (copy constructor and copy operator) are illegal due to various problems raised by redondant information.
